Adopting CPU AT32F403ARCT7 with the structure of ARM - allows CPU clock speed. 240MHz and the max PWM switching frequency 45KHz improves the motor RPM. Programmable via ESC Tool to be compatible with multi-types of motor, different battery voltages and many control ways. Programmable via remote controller VX4 (remote firmware version: VX4_V1.4.0 or above). Supporting motor FOC with low working noise and smooth starting. Supporting Real-time data and fault alerts. Supporting adaptive variable PWM frequency control. Supporting sensor mode(HALL) and sensorless mode(IPDS, HFPI). Supporting control types: Current, Duty Cycle, Speed control, Position Control Protection functions: low and high voltage protection, over-current protection, temperature abnormally protection, mosfets over-temperature and over current protection, battery over discharge protecting, motor over-temperature protection.
